Will I still get my period, could I be pregnant?

I missed a pill 48 hrs and had unprotected sex in that time. This was within my first week of pills, took Friday, missed Saturday and didn't take another until bedtime Sunday. I then missed two pills the following weekend, this started bleeding. I took pills again that sunday until today, Wednesday and I am still bleeding. It's gotten lighter but still happening. I am due my period a week from now..will I still get my normal period if I have been bleeding for a few days? I've also been feeling moody, tired, light cramping, itchy stomach and my boobs feel bigger. Should I be worried?
